Latest Patents

One of her latest patents is titled "Extension of dynamic range for continuous tone laser printers." This innovation extends the dynamic range of a continuous tone laser printer by directly modulating a diode laser while simultaneously modulating the optical output of the diode laser with an acousto-optic modulator. The digital image value is input to two look-up tables (LUTs) that convert the image value to two digital words. One word sets the power level of the diode laser, while the other sets the diffraction efficiency of the acousto-optic modulator (AOM). The first look-up table is constructed from the performance characteristics of the diode laser, and the second is based on the performance characteristics of the AOM. The outputs from these look-up tables are applied to respective digital to analog converters, which drive a voltage to current driver for the diode laser and a radio frequency driver for the AOM. The resulting power of the writing laser beam is a linear function of the input image value.

Another notable patent is the "Light beam intensity controlling apparatus." This device includes an acousto-optic cell that receives an input light beam and produces an undiffracted or zero-order light beam and a diffracted beam in response to an RF signal at a predetermined frequency. An error signal is generated, which reflects the differences in the intensity of the zero-order beam from a desired level. This error signal is utilized to control the amplitude of the RF signal, thereby adjusting the intensity of the diffracted and zero-order beams to maintain a relatively constant zero-order beam intensity.
